APPARATUS FOR DR AWING OFF LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 725,211, dated April 14, 1903.

Application filed July 23, 190i.

To all whom, it may concern/.-

Be it known that I, ALFRED BRAKE,a subject of the King of Great Britain and Ireland, residing at Wellington, in the Colony of New Zealand, have invented Improvements in Apparatus for Drawing Off Liquids, of which the following is a specification.

This invention has reference to improve ments in that kind of apparatus for drawing off liquids in which a vessel, commonly called an intermediate vessel, is normally in comm unication with the liquid -stori'ng vessel through a passage controlled by an inletvalve, so that it will stand charged-with liquid ready to be drawn off, is provided at its lower end with a discharge passage that is normally closed by an outlet-valve, and is adapted to have its upperpart, which is normally disconnected from the external atmosphere, placed in communication with such atmosphere when required through a passage controlled by a valve, so as to allow of gas under pressure within the vessel being released previous to opening the liquid-outlet passage in order to prevent the liquid being discharged under too great a pressure.

The present invention has for its object to provide a simple, reliable, and easily'worked apparatus of the kind referred to whereby aerated liquids can be rapidly drawn off in' an advantageous manner and cool condition from the intermediate vessel.

With this and other objects in view the invention consists in certain novel features of construction and combinations and arrangement of parts, all as hereinafter fully de-j scribed, and more particularly pointed out in the claims. I a

In the accompanying illustrative drawings, Figure 1 is a vertical section on the line A A of Fig. 2; and Fig. 2 is a front elevation, partly in section, on the line B B of Fig. 1, showing apparatus constructed according to this invention for drawing off aerated liquid in a cool condition.

a is a stationary intermediate vessel provided with a liquid-inlet pipe 27, terminating within the vessel in an opening 0 (hereinafter called the liquid-inlet passage) and controlled by a liquid-inlet valve d,with a liquidoutlet pipe 6 extending from its bottom part a and controlled by a liquid-outlet valve f,

Serialllo. 69,416. (No model.)

' ahd with an opening g, that extends through its top part a and serves for the exit of gas under pressure from the top of the vessel previous to drawing off the liquid contents thereof and for the entrance of air during such drawing off, this passage, hereinafter called for distinction the gas-passage, being controlled by a valve 71, hereinafter called the gas-valve. it is a valve-rod that extends through the top of the vessel and is adapted when depressed by suitable operating means to first open the said gas-valve h and allow gas under pressure in the top of the vessel to escape, to then cause or allow the said inlet-valve d to close and cut 013? the supply of li uid to the vessel, and finally to open the outlet-valvefand allow the liquid contents of the vessel or a part thereof to be drawn off, the valves moving in the reverse order when the valve-rod is raised, so as to first close the liquid-outlet, to then open the liquid-inlet, and finally to close the gas-passage.

In the example shown the intermediate vessel a is made in three main parts, viz: an intermediate part a and top and bottom parts a, and a that are secured together in a fluidtight manner in any convenient Way-as, for instance, byinterposing packing-rings m and n of suitable material, such as india-rubber or leather, between the adjacent parts a a a surrounding the intermediate part a, which may be of cylindrical shape, as shown, with a sleeveo, that is screwed at its lower end in a socketp on the upper side of the lower part a and screwing the top part a to the top of the sleeve. By this construction the intermediate vessel can be easily built up and can also be easily taken apart when this may be necessary to gain access to the parts within it. The liquid-inlet pipe I) is screwed into a socket g on the bottom part a, so as to be in communication with a pipe b, that is preferably cast in one piece with the said bottom part and is adapted to be connected to a liquid-supply pipe extending from the vessel containing the main supply of liquidto be drawn oii. The inlet-pipe 1) extends upward into the vessel a, its delivery end being bent over and enlarged to form a valve-chamber r, the bottom of which is provided with the liquid-inlet passage 0, controlled by the liquid-inlet valve d. This valve is provided with a downwardly-extending stem t, that is preferably guided by a tube u, fixed in the bottom of the valve-chamber rand serves as the liquid-inlet passage. The liquid-outlet pipe 8 is inclined downward, so that liquid will readily drain away therefrom, and is bent to form a spout. Its upper end is controlled by the liquid-outlet valve f, which is made as a lift-valve and isadapted to be raised by one arm 1; of a lever that is pivoted to a lug a; on the bottom part a of the vessel and has its other arm to terminating below the valvechamber 1".

The gas-valve h is located within the "essel a and is fixed to the valve-rod 70, which extends through the gas-passage g and works at its lower end in a guide 1 on the inlet-pipe b, its upper end being connected to suitable operating means, which in the example comprises a crank-pin 2 on a spindle 3, provided with an operating-handle 4, the arrangement being such that when the valve-rod is depressed snfficiently it will open the gas-valve it suddenly, as and for the purposes hereinbefore described. To the valve-rod is fixed a rectangular-shaped frame 5, that embraces the valve-chamber 7 and is provided with a projection 6, which when the gas-valve his closed acts against the valve-stem zfand holds the liquid-inlet valve d in its raised and open position. The said frame 5 is arranged above the arm to of the valve-operating lever o (to, so that when it is depressed it will, after opening the gas-valve h and allowing of escape of gas under pressure from the top of the vessel and releasing the inlet-valve d and allowing the same to be closed by gravity, aided by the pressure of the liquid in the inlet-pipe I), act upon the arm to of the lever 12 w and depress the same, so as to open the' liquid-outlet valve fand allow the liquid contents of the vessel or a part thereof to be drawn off. When the valve-rod is raised, the outlet-valvefwill close by gravity, the frame 5 will raise and open the liquid-inlet valve d, and the gas-valve 77. will be caused to close the gas-passage g.- To insure the closing of the liquid-outlet valve f, the arm 10 of its lever may be formed with a slot 7, into which extends a pin 8, carried by a bracket 9 on the under side of the frame 5, the arrangement being such that in the event of the arm w of the lever remaining down when the valve-rod rises the pin 8 will lift such arm and cause the outlet-valve f to close.

The interior of the vessel a and the various devices therein should be of material that will not readily affect in an injurious mannor the liquid admitted thereto. For this purpose the intermediate portion of the vessel may conveniently be of glass. If of metal, it should be lined with material such'as tin or silver applied by heat. The upper surface of the bottom part ct and the lower innersurface of the top part a should be similarly covered with protective material. The inlet-pipe b may be of silver or tin, as also may the inlet and outlet valves 01 and f, (except their faces, which may be of leather or indiarubber,) the inlet-tube u, and the lower part of the valve-rod k and theframe 5. The gasvalve h may be of india-rubber.

For the purpose of enabling the liquid contents of the vessel ato be drawn off in a cold condition the said vessel is fixed within a receptacle 10such, for example, as a marble boxthat is charged with ice or other cooling agent,that surrounds the said vessel. The vessel may conveniently be fixed to the front wall of the receptacle 1O by-means of its liquid-outlet pipe 0, which for this purpose is formed with a shoulder 11 to bear against the inner side of the said front wall and is provided with a screw-nut 12 to bear against the outer side of the said wall, a packingring 13 serving to insure a good joint between the connected parts without injuring the wall of the receptacle. In this case the valve-opcrating spindle 3 is mounted to turn,but not to move endwise, in abearing 10 in the said front wall of the ice-receptacle, its outer end being provided with the handle 4. A spring 14 may be provided to cause the handle to automatically return to its normal position and raise the valve-rod after the same has beendepressed and released, and a stop 15 may be provided to limit the turning movement of the handle 4: in a downward direction.

It will be evident that various changes can be made in the details of construction of my apparatus without departing from the spirit and scope of the invention solong as the relative arrangement of parts shown in the drawings or the mode of operation described in the specification is preserved.
